I've already mailed USB Gecko support about this. Basically it looks like the same issue I saw when trying to run this with the Freeloader on my (now sold) Gamecube. I did get it working with a XenoGC modchip, so apparently it does something neither Freeloader nor GeckoOS do.
Game boots and you can view extra content like interviews, etc., but when you try to boot one of the games you get the standard "An Error Has Occurred. Reset your system, blah blah blah" message. Also tried GCBooter, but that did the same thing.
Not sure what the issue is; hopefully it's not too tough to crack?
Note that I have a PAL Wii with the latest 3.3 firmware installed.
No idea what the issue could be? It would be super to get this sorted; running US Gamecube games appears to be all I'm going to be using GeckoOS for once I get a Japanese Wii. It would be a shame if there was only one I could do that with!
This still isn't working as of 1.9.
Not sure what's different between Midway Arcade Classics 1, which works fine, and this game, but it seems odd.
